SLIDING-JAW WRENCH.

Application filed February 26, 1923. Serial No. 621,195.k

State of Minnesota, have invented certain new and useful Improvements in a Sliding- Jaw Wrench, of which the following is a specification.

My invention relates to an improvement in wrenches of the sliding jaw type, the primary object thereof being the provision of such a wrench that is comparatively simple of construction, extremely inexpensive of manufacture and of such a nature as to permit the sliding jaw to be adjusted in a simple and expeditious way. Y

l/Vth the aboveand other objects in View as the nature of invention is better understood, the same consists of the combination and arrangement of parts shown and described.

In the drawings wherein the reference numerals indicate corresponding parts throughout the several views Figure 1 is a plan view of a wrench constructed in accordance with this invention.

Figure 2 is an elevational view one side thereof.

Figure 3 is a longitudinal transverse cross sectional view of the wrench shown in the other figures. v

Figure 4 is a perspective of the sliding jaw per se, and

Figure 5 is a similar view of the sliding latch member forming a part of my invention.

Referring to the drawings in detail, 5 designates the shank or handle, preferably ilat shape and being enlarged at one end for forming a head 6, the front end of this head preferably extends at an angle to the longitudinal axis of the handle or shank 5 and formed at onel end with a forwardly projecting jaw 7.

The said head 6 is formed with a transversely extending T-shaped slot 8 within which is slidably disposed the T-shaped head 9 of a sliding jaw 10. The opposite sides of the head of the said 10 are channeled as at 11 for receiving ends of pins 12 carried by the head 6 of the said handle or shank 5 for limiting the outward sliding movement of the movable jaw.

rlhe handle or shank 5 is formed with a relatively long longitudinally extending angular shaped bore or channel 13, the front end of this channel being of increased ywidth for forming a pocket 14, this pocket communicating at one end with the said T1 shaped'channel 8 of thehandle head 6. The opposite inner end of thisk pocket 14 is formed with beveled shoulders 15. Slidably disposed within the bore or channel f '13 is an angular shaped lrod 16, the front end thereof being headed as at 17 and similar slidably disposed within the pocket 14, the front end of this head extending at an angle and formed with rack teeth 18, whilst the inner end thereof is formed with beveled shoulders 13. The opposite end of the said angular shaped rod 16 is formed with a projecting pin 20 which engages within one end of a coil spring 21 within the bore or channel 13 and adapted for normally projecting the head 17 of the rod 16 outwardly of the pocket 14.

The inner face of the head 9 of the sliding jaw 10 is racked as at 22, the racked end of the rod'16 adapted for normal en gagement therewith for preventing an outward sliding movement of the jaw 10.

Adjacent to the inner end of the angular rod 16, there is formed a thumb piece 23 which extends outwardly through a slot in the handle or shank 5 and is adapted to be engaged by the thumb of the operator for retracting the rod 16 within the channel 13 for consequently disengaging the racked end of this rod from the racked surface 22 of the sliding jaw head 9 so as to permit this jaw to be slid to the desired position with respect to the stationary jaw 7.

In view of the above description, it is believed by me that the advantages and operation of a wrench of this character will be readily appreciated by those'skilled in the art, and although I have herein shown and described the preferred embodiment of my invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

A wrench comprising a handle member having a fixed jaw formed thereon and provided at its end with a pocket the side walls of which are disposed parallel with the median longitudinal axis of the handle, the said handle member being further provided with transversely disposed grooves which are inclined with relation to the median longitudinal axis ofthe handle, the handle member being further provided with a channel which communicates at one end with the pocket and which is disposed with ts'axis in alinement with the median longitudinal axis of the handle, a rod slidably mounted in the channel and fitting snugly therein and being angular in transverse section whereby the said rod is restrained against turning movement in the channel, a spring disposed iu the channel and interposed between the inner wall thereof and the inner endV o'rl the rod and being under tension to normally hold the rod toward the grooves in the handle'member, a head carried by the rod and disposed withinfthe pocket and completely bridging the same transversely, said head being provided with ratch/et teeth,

retirara a jaw slidabljfT mounted upon the handle member and having at its opposite sides flanges which are slidably received in the grooves7 said jaw being provided at its inner edge with teeth adapted to engage in the teeth upon the head of the said rod, the said slidable jaw having a slot which is disposed with its longitudinal axis at an acute angle to the median longitudinal dimension of the handle, a pin secured at its ends to the handle and passing transversely through the slot and manually operable means carried by the rod and projecting through a slot in the handle forr releasing the teeth on the head from engagement with the teeth on the jaw.

In testimony whereof Iaiiii; my signature.
